Subwoofer issues! or box. unsure.

Hey, i'm new to this forum but i really need help.
See i just bought these 2 kicker comps 15's for 100 bucks brand new! what a steal right, well i thought. I have a alpine amp500.1 or something simular to that its a really tiny 1 channel amp that puts out 500 watts. All my wiring is good except my RCA cable does have its issues.
Anyways i had it all set up and have been driving around for about 2 days with no issues sounds amazing! well today for some reason everytime it really hits the hard beats from my left speaker i hear an intense rattle? Oh i do have these 15's in my lil 95 ext cab S10. the rattle ruins the whole song! but it still hits really hard. The box was brand new ordered online and shipped. And it just randomly occured and it wont go away. does anyone have any advice on what the issue might be? Everything is brand new, and this problem just started to happen.
Thanks!

That's what I'm thinking. At least it's not the sub. Lesson learned: prefab ported is not the way to go. Get in touch with @double 07 ; and see what kind of box he can build you. At least then they'll be made for your subs and should sound INFINITELY better than the prefab.
